They are perfectly reliable after you replace everything. I was so paranoid of having the cylinder liners slip on the disco, I replaced the head gaskets and rebuilt the heads as preventative maintenance. Each model seems to have it's Achilles heel that you need to fix right off the bat to have...
I thought about about buying a defender (not the new abomination) to replace the D2, but wanted something dependable so I ordered the gladiator instead. There's something about those old Land Rovers that that makes them hard to let go.
The D2 is a force to be reckoned with off road, especially if you can get one with the center diff lock. I had some slightly taller tires on mine, but it seemed to do better in the ground clearance department than my gladiator.
Here's the Land Rover it replaced for reference. Horrible gas mileage and hated the mountains, but only rode on a flatbed when it was being hauled out of state to the new owner.
Went on a vacation about 10hrs away and the gladiator started having a heavy misfire about 3hrs from home on the way back. Currently sitting in a save-a-lot parking lot with my family and our expedition trailer waiting for a rescue. Guess I'll have to make a return trip later to collect the Jeep...
I've never used this company, but it might be worth looking into for getting a batch of these made:

I can also help you make a .stl of the part if needed
The gladiator is the best off road pickup you can get and a really fun summer vehicle if you like taking the top/doors off. If neither of those appeal to you, I would probably be looking at other trucks.
Wish you had resources to keep developing the 3.6 platform since you took on a lot of liability here and don't seem to be doing this for your own personal gain. This situation would definitely test anyone's fortitude.
Shhh, you don't want to upset the diesel brigade any more than they already are. In all seriousness, there are probably lots of people who buy a diesel for light duty use and never have a problem. They obviously run very hot, but it's probably too early to tell how that will affect the...
Getting a synthetic rope will help with the added weight, and some bumpers are lighter than others. I have a winch because my family likes going to remote places and sometimes there's no substitute for what a winch can do.
Another option in that 2k price range is the AEV 2.5" lift. It comes with bilstein 5100's which may not be quite as nice as the fox shocks, but they are custom valved and everyone seems to agree the kit is top notch.
So here's a quote from someone with real-world experience who says the diesel can't tow in the heat and wouldn't be safe to drive. Spoiler alert, it's you:
It's going to depend on how your truck is set up and loaded, but most people seem to feel that 30° is a good limit. I start getting uncomfortable around the 15-20° mark though, because it sure feels like a lot more than that in the moment.
